Plan
Set up each brand once: its voice, its channels and its media. The Automation Planner then sets how many posts go out per day on each platform, the image and video mix, and the exact time of every post.
Meton Labs builds SignalFlow, a review-first workspace for marketing agencies. Plan posts for each client brand, draft them with the AI model you choose, approve every word, and publish on schedule through official platform APIs.
Every post in SignalFlow moves through the same four phases. AI does the drafting. A person makes every decision that reaches the public.
Set up each brand once: its voice, its channels and its media. The Automation Planner then sets how many posts go out per day on each platform, the image and video mix, and the exact time of every post.
When a post is due, SignalFlow drafts one version per channel in the brand's voice. You choose the model: Gemini, ChatGPT, the OpenAI or Gemini API, or write it yourself.
Every draft lands in a review inbox as "Needs review". Before anything can be scheduled, a preflight check confirms the channel is connected, the media is reachable and the post type is supported.
Approved posts publish through the official Meta Graph API. Each job carries an idempotency key, so a retry can never post the same thing twice, and every result is recorded against the brand.
Agencies run many brands at once. SignalFlow keeps each brand's queue, voice and approvals apart, and shows exactly why a post is or is not ready to go.

Illustration with sample data. The brand and post shown are examples, not a customer.
Organise work as client, brand and channel. Each brand has its own voice, media library, schedule and approval history.
Posts per day, image and video mix, and a time for every post, set per platform. Due posts become drafts for review, never automatic posts.
Draft with Gemini or ChatGPT subscriptions, the official OpenAI and Gemini APIs, or by hand. Every draft records which model wrote it.
Nothing is published without a human approval. Preflight blocks posts with missing media, a disconnected channel or an unsupported format.
Facebook Pages publish through the official Meta Graph API. Idempotency keys and retry states stop duplicate posts when a network call fails.
Platform tokens are stored in a user-only file on your computer. The app interface never reads them, and SignalFlow never copies browser cookies or passwords.
We list a capability as live only after it has worked end to end on a real account.
Status as of October 2026. Platform names belong to their owners. Meton Labs is not affiliated with Meta, Google, OpenAI or Anthropic.
Meton Labs is founder-led. Claude is part of how we design, build, review and run SignalFlow every day.
Claude helps us design features, write and refactor the Electron, React and Python code, and keep the architecture documents current.
Claude reviews changes before they ship, including work written with other tools, and reports its findings with an explicit pass or fail.
Claude writes test plans, reproduces bugs, finds root causes and runs release checks on the packaged app.
Claude helps us run the company itself: infrastructure, documentation and this website.
Meton of Athens noticed that 19 years on the sun's calendar almost exactly match 235 cycles of the moon. After that span, the sun and the moon meet again on the same date. We build for that kind of alignment: the right message reaching the right audience at the right moment.
Our mark follows the same idea. Every circle in it is sized by a power of the golden ratio, and the sun sits exactly on the horizon line where the arches begin.
Meton Labs is an independent software company based in Vietnam. We build tools that help marketing teams and agencies publish consistently without giving up control over what goes out.
We are opening SignalFlow to a small group of marketing teams and agencies. Tell us which brands you manage and which platforms you publish to.
